Local dyadic fractional Sobolev spaces: paraproducts, commutators, and the algebra property

Valentia Fragkiadaki, Mishko Mitkovski, Cody B. Stockdale

We characterize the boundedness and compactness of dyadic paraproducts on local dyadic fractional Sobolev spaces, . We apply this result to establish the algebra property for…

Paraproducts, Bloom BMO and Sparse BMO Functions

Valentia Fragkiadaki, Irina Holmes Fay

We address bounds for paraproducts in the Bloom setting. We introduce certain "sparse BMO" functions associated with sparse collections with no infinitel…
